Show original supplier description
The Patriot Exhaust H8412 is a full-length header set engineered specifically for 1971-1973 Ford Mustang and Cougar vehicles powered by the 351C 2V engine. These headers feature 1-3/4 inch primary tubes designed to increase exhaust scavenging and improve engine breathing compared to restrictive factory manifolds. Built from steel, these headers provide a durable foundation for high-performance street applications. The full-length design is optimized for power gains across the RPM range, making it a common upgrade for vintage muscle car enthusiasts looking to enhance their vehicle's output. This specific part number is designed for the 351C 2V (2-barrel cylinder head) configuration. It is compatible with both automatic and manual transmissions, including the C6 automatic. Buyers should verify their engine port configuration, as this header is not compatible with the 351C 4V (4-barrel) cylinder heads.
